Abstract

To provide a shatter prevention film of a protective glass of a liquid crystal display device capable of being formed easily and excellent in properties such as shatter prevention performance. A shatter prevention film arranged on protective glass of a liquid crystal display device, wherein the shatter prevention film is formed of a cured body of a photo curable resin and has a bonding strength of at least 0.3 N / 25 mm wide and an elongation of at least 20% when measured in accordance with JIS A 5759.

Description

technical field [0001] The present invention relates to a shatterproof film for a cover glass of a liquid crystal display device, which film imparts shatterproof properties to the cover glass on the viewing side surface of a liquid crystal display device when the glass is impacted and broken. Background technique [0002] When the glass breaks, in order to prevent the glass from shattering, a known method is to stick a shatterproof film on the glass surface, and this film includes a resin film such as polyester as a base and an adhesive applied to the resin film (for example, Japan Unexamined Patent Publication (Kokai) No. 2004-338365). [0003] When applying this anti-shatter film to the glass surface, the film must be cut according to the glass specification, and it is difficult to apply the film evenly on the entire surface of the glass without trapping air bubbles between the film and the glass and without wrinkling superior. Especially when the glass surface has conca...
